Recent romantic partners always want to shower together and I couldn’t imagine anything more irritating. How do people get themselves properly clean while someone else is there fondling you? Sure, they can help scrub your back but maybe I need some space and privacy to clean all the BITS, you know?
So annoying. But it keeps the “passion alive” so fine, I’ll do it.
Personally I don’t regard showering with my partner as particularly sexually exciting but more as a way to enjoy intimacy and being close and vulnerable with one another.
